3^y power because it was stated that y is greater than x so a number to the power of y will always be greater than a number to the power of x. Btw that looks a lot like the one I have lol
Answer: Part A = 12 candles per hour
Step-by-step explanation:
48/4 = 12
Step-by-step explanation:
18+ 5(2x + 5) = 12
18 + 10x + 25 = 12
43 + 10x = 12
10x = 12 -43
10x = -31
x = -3.1
Answer:
Therefore, the side lengths 10, 14, and 15 form a triangle.
Step-by-step explanation:
The Triangle Inequality Theorem defines that if we are given the three sides of a triangle, then the sum of any 2 sides of a triangle must be greater than the measure of the third side of the triangle.
The three conditions that need to be met for any triangle with the side lengths A, B, and C.
Given the side lengths of a triangle
Let us check whether it satisfies the three conditions.
10+15 > 14 → TRUE
10+14 > 15 → TRUE
14+15 > 10 → TRUE
As all the conditions are met. Therefore, the side lengths 10, 14, and 15 form a triangle.
Answer:
We reject the Null and conclude that the mean costs of a meal at fast food restaurants in two different cities are different.
Step-by-step explanation:
Given :
City n x s
A 26 $4.05 $0.55
B 32 $5.15 $0.85
H0 : μ1 - μ2 = 0
H0 : μ1 - μ2 ≠ 0
n1 = 26 ; x1 = 4.05 ; s1 = 0.55
n2 = 32 ; x2 = 5.15 ; s2 = 0.85
Tstatistic :
(x1 - x2) / √(s1²/n1 + s2²/n2)
(4.05 - 5.15) / √(0.55²/26 + 0.85²/32)
-1.1 / 0.1849668
= - 5.947
Using the smaller n;
df = n - 1 ; 26 - 1 = 25
Pvalue = (-5.947, 24)
Pvalue = 0.000001
Since Pvalue < α ; We reject the Null and conclude that the mean costs of a meal at fast food restaurants in two different cities are different.
